I To all whom it May concern.-

Be it known that I, NIoKLAS FRANZEN, a citizen of the United States, residing at Mo nongahela city, in the county of Washington and State of Pennsylvania, have invented or discovered a certain new and useful Improvement in Methods of and Machines for Making Wire-Glass, of which improvement the fol lowing isa specification. -.,.l\/Iy invention relates to improvements in methods of and machines for making wireglass; and the object of my improvement is simplicity of structure and efficiency in operation.

Wire-glass in commercial form is a sheet or plate of glass having embedded within it a netting or fabric of fine iron wire.

It will be understood that by the machine of my present invention not only wire-netting, but other substances in other forms may be incorporated within a sheet ofglass. While not limiting my invention in this regard, I shall for the sake of simplicity designate theincorporated substance as wire or fabric. Y

In the accompanying drawings, which form part of this specification, Figures 1, 2, and 3 show diagrammatically in longitudinal sectionand in successive operative position a machine which embodies my invention. Figs. 4 and 5 are similar views illustrating modifications.

' alaver may, as shown at?) in Parts which are repeated in the several fig- .ures bear the same reference-numerals in each case.

The machine consists, essentially, of a cast: ingtable 1, whereon a sheet of wireglass may be formed and whereon the finished sheet may be supported and conveyed to the annealing-oven, andof means for forming a component layer of the sheet above the casting-table and for spreading molten glass upon the casting-table and for simultaneously incorporating the glass so spread with the independently-formed layer to form the finished sheet.

The means for forming a layer above the casting-table consists of a pair of rolls 2 and 3, so arranged as to form between'them a hopperdike receptacle-wherein molten glass may be teemedland by suitable rotation of the rolls formed into such component layer. One of the rolls which thus cooperate to form ig. 4, cooperate with table 1- also to spread molten glass thereon and incorporate the-glass so spread in a separate'roll 4;.

spread molten glassupon thez-casting-table 1 the spreading-roll and the table'mnst be relatively movable,"- and in this respectmy-preferred construction is thatwhich-the draw ings show, cas'tingtable 1 being mounted upon wheelsto advance beneath the rolls, which are preferably mounted in relatively immovable positions. Rolls 2 and 3 (or 3*) are suitably spaced from one another to produce a layer of desired thickness, and roll 4 1' to form the. finished sheet.

shown in Figs. 1-4 a chute 8 for the wire fabricis' provided to feed the fabric over, the surface of roll 2 and into thehopper-like receptacle formed by rolls 2 and 3. Means maybe provided for placing the fabric as it under tension in order that the. wire may lie therefrom to allow an appreciable thickness of glass to pass beneath the Wire, which would result ina displacement of the wire in the finished sheetsl Convenient. means to 8 and to exert a binding or holding actionupon the wire as it passes beneath the roll;

from between rolls 2 and 3 will effect a ten sion upon the wire hel'd above byroll 7'. Roll 7 is conveniently placed at or near the delivery edge of chute 8, as shown in the drawings.

In the form of "my improved machine It will be'understood that-in order to.

is progressively fed over the surface of r0112 smoothly on the surface of roll 2 and not rise I the end stated may'be found'in a roll 7, arranged to cooperate with'the surface-of chute The weight'or drag of the glass as it passes In the form of machine shown in Fig. 5the wire fabric is introduced not into the pass 5 this end chute 8 is'suitably arranged to feed the fabric to the pass beneath mil 4*, as

shown in the said figure.

.ment in passing downward and from buckling upon the table, a guide-plate 5 may be introduced rearward of roll 4'1 (The direction of movement is indicated by the arrow a.) This serves to insure the proper passage of the layer forward between rolls 2 and 3 downward to the pass between the castingtable and the uniting-roll. It will be understood that this guide-plate is employed only when the spacing of the parts'and conditions of use make it necessary or desirable.

The operation of this machine may be briefly described. The operative parts bein in the position shown in Fig. 1, Wire fabric X is carried down chute 8, beneath tension-roll 7, (by which it is also fiattenech) over the face of roll 2, and downward into the pass between rolls 2 and 8. A batch of molten glass B is then teemed into the receptacle which rolls 2 and 3 form, whereupon suitable rotation of rolls 2 and 3, which will be accompanied on the advance of table 1 in the direction indicated by arrow by means well known in the art, will effect the formation of .i,.la.yer of glass C, having incorporated in its rearward face the wire fabric. It will be observed that since the molten glass B is spread upon the wire as it lies upon the face of roll 2 the wire is incorporated in the glass without strain. It will be further noted that the tension which is exerted on the wire will be sufficient to kee the latter lying smooth upon the face of re 1 2. Meanwhile a second batch of molten glass B is teamed upon the forward portion of table 1. The progress of the table causes roll 4 to retreat and spread this molten glass, and as this roll retreats it carries upon its face the layer C, with the wired surface exposed. This advance of roll 4 not only spreads the molten glass, it simultaneously unites the glass with the wire-containing layer and incorporates the whole into the finished sheet of wire-glass E.

The operation of the machine in the form shown in Fig. 4 is identical with the de scribed operation of the form of Fig. 1, roll 3 in this case performing the parts which in the form already described were performed by rolls 3 and 4. The operation of the form shown in Fig. differs only in the circumstance that the fabricAis introduced between the layer C (which in this case is formed without wire) and the batch of glass D as l felt a, faced or covered with layer (1'', re-

treats to spread the molten glass D and incorporate. it with layer C. to form the finished sheet. The wire so interposed will ooeupy the position in the finished article,

which it occupies when introduced as in Fig.

1; but it will be noted that it comes into contact with batch D when in molten condition and not into contact with batch B when in molten condition. The fabric may be held under tension by roll 7 cooperating with chute 8', for substantially the same purpose that it is placed under tension in the form of machine shown in Fig. 1.

I claim as my invention 1. In a machine for making plate-glass, the combination of a casting-table wl'iereon a sheet of glass may be formed, and carried,-

molten glass to layer form upon said castingtable and for progressively uniting such lastnamed layer as it is spread with said Wireincluding layer, substantially as described.

in a machine for making wire-glass, the combination with a casting-table whereon a sheet of wire-glass may be formed and carried, means for forming above said. castingtable a wire-including component layer of the finished sheet and means for receiving such Wire-including component layer and for spreading molten glass to layer form upon said casting-table beneath said wire-including layer, substantially as described.

4. in a machine for making wire-glass the combination of a castingtable whereon a sheet of wire-glass may be for ed and carried, means for forming upon asuitable surface above said casting-table a wire-including component layer of the finished sheet, means for feeding wire fabric under tension over such suitably-arranged surface, and means for spreading upon said casting-table molten glass to layer form and progressively uniting said last-named layer with said wire-including layer as the layer upon the casting-table is spread, substantially as described.

5. In amaohine for making wire-glass, the combination of a castin -table, means for forming above said casting-table a componcnt layer of the finished sheet, means for spreading molten glass to layer form upon said casting-table and for progressively uniting with such layer as it is s read upon the casting-table the layer forms above as aforesaid, and means for guiding such layer formed above in its descent to the casting-table, substantially as described.
